Serving as the "skeleton" within power, telecommunications, and industrial facilities, the primary function of cantilever cable tray supports is to ensure-through scientifically engineered support and arrangement-that cabling systems maintain adequate heat dissipation space and safe clearance distances during operation.
In engineering practice, strict adherence to installation standards constitutes the fundamental baseline for ensuring system stability. As a baseline requirement, vertical spacing between layers must be flexibly adjusted according to voltage levels: spacing for control cables is typically maintained at a minimum of 120 mm, while that for power cables should be expanded to between 150 mm and 300 mm to satisfy insulation and heat dissipation requirements. Second, to prevent permanent deformation caused by the cables' own weight, horizontal span lengths must be precisely controlled-based on cable diameter-within a range of 0.8 meters to 1.5 meters. Furthermore, with regard to safety and durability, two critical technical prerequisites that constitute non-negotiable "red lines" during project acceptance are the establishment of electrical continuity for grounding across metal support structures, and the application of hot-dip galvanizing as an anti-corrosion treatment for use in harsh environments.
